A lot of the "fish finders" and a lot of the "chart plotters" out there use proprietary software running under a CE shell. Actually Oziexplorer makes for great marine use once you convert the maps. And my Skeyepads all run on 12V directly, so they make great hardware (using a sunshield of course) on the boat. They are easy to mount since they come with car cradles too. The have open serial ports on them...so interfacing a depth transducer isn't a problem. The problem is that there is no CE software that I know of that will display (convert the serial signal) the depth. It's just a matter of timing really...I mean from the time of the generated pulse to the time of the received echo is all that it takes to measure the depth. So the CE application would simply do that...read the time the signal is sent to the time the echo is received in milliseconds and the calculate the depth based on that info.
Hm... by the sound of it, maybe you can do some eMbedded Visual C++ / Basic COM programming then!
